Recent high-pressure testing by Ansaldo showed the turbines would operate with up to 70 percent hydrogen without power or efficiency derating, according to the release. Equinor works on oil, gas ...

Efficiency gains. Increasing combined cycle gas turbine (CCGT) efficiency to 70% and simple cycle efficiency to more than 50%.

This high-pressure steam then expands through a steam turbine, creating power. In combined cycle gas turbine power plants, natural gas or coal syngas is burned in a combustor with compressed air.

And while the GT36 H-Class turbine can already be operated with a volumetric hydrogen content of 0% to 50% (and the GT26, up to 30%), recent full-scale high-pressure tests showed the “the ...

Scientists of Peter the Great St. Petersburg Polytechnic University (SPbPU) developed turbo expander electric generator operating on high-pressure natural gas. Natural gas being compressed at the ...

Tension over giant turbines that Moscow blames for the reduction of flows via the Nord Stream 1 gas pipeline has put the focus on the equipment it needs to operate.
